Hi everyone,
I have to build a version of the MFA board. Can I replace the XS1-U8A-64 controller, which uses the FBGA package, with a controller which I can solder to my board?
I hope you can help.
Best Regards,
Chris

Hi Chris. My "2 bits"...
a) the XS1-L8A-64-LQ64-C5 should be similar but in a TQFP package which may be appealing at initial glance. However, this device is missing the required USB PHY so you will have to follow the respective design notes on how to apply an external USB PHY onto this processor. In addition to the review of the code which may need some tweaking if using this component. Finally, the TQFP version of the package may still not be suitable as it contains a metal belly which requires to be properly soldered (perhaps you could use a hotplate for this purpose).
b) BGA soldering is not so bad to process. There are many internet articles on this subject. If you are involved in this field or plan to be, consider to review some of the relatively low cost SMD table top ovens with profiling support from China or similar but do read the respective reviews before ordering a unit. There are far too many offshore suppliers who will take the funds and not offer follow up support.
In no particular order:

Soldering a fresh BGA onto a PCB is a different process than removing and/or reballing to replace the component so be sure to be clear on your purpose with the supplier. Also, the unit must support the RoHS temps which are common to the XMOS devices.
c) You could ping a local SMD assembly house for assistance on this subject. If your budget permits it, there are many similar houses in Asia who will build your project even in single qty. Just be sure to keep some secret sauce from such submissions to avoid IP theft.
For us, we have a 9 zone SMD oven in house. Is there a demand for a BGA to through hole conversion board ? It will be best for signal integrity and software development, etc. to consider to learn how to mount the original BGA device directly onto your PCB.
Hope this helps.
